I went to take some shots of the moon rising off my porch window yesterday and when I downloaded them to the computer I realized that they were jpegs. I went to see the camera setting and sure enough it had slipped itself to jpeg and out of RAW. This is the second time the camera has done this to me. So I know it may be more than a fluke. I'll have to be keeping a watchful eye on it form now on. Here is a shot I got last night.

Hand held
Nikon 35-70mm f2.8 AF lens
D750
ISO 6400
1/8th of a second
f2.8
lens at 70mm

My only regret is that I do not have it in a RAW file.

I can see you're new at this, huh?

I used to constantly have this problem with my D7100.
Finally, I realized that I was pressing a wrong button on the left side of the back of the camera.
When I thought I was changing the ISO, I was actually changing the image "quality"
from Raw to Jpeg.
The solution for me was to change the way I select the ISO. I now use the "easy" method
and use only one of the dials on the upper right of the camera, rather than using the button
on the back plus the dial.

Same thing has happened to me on night shots in Patagonia. In the dark I had inadvertingly pressed the quality/+ button which switched setting from RAW to jpeg, rather than the ISO/- button just below it on the left rear side of the camera. Didn't realize or figure out this mistake until after I finished my shoot and starting looking at the metadata. An "expensive" slip of the finger!

If there is a button that is being accidentally hit to change it to jpeg, I have not not been able to find it. The only way I know how to do it is to go into the menu and go through a few steps to do it. Personally, I feel it's a flaw in the software.

I checked the camera and hitting the quality on my D750 only pops up the option to change the setting. To do so, you have turn the back wheel too. There is no way that happened.

What I was doing on my D7100 was attempting to change the ISO while keeping my eye to
the viewfinder. I would press a button and rotate the dial thinking I was pressing the ISO button
but I was actually pressing the "quality" button.

Gotcha and understand. I do not make changes like that blindly; only if I can see in the viewfinder what I did would I do it that way.

Well, I learned my lesson, but it was a very frustrating mystery to figure out.
I still have my D7100 and D750 set up so that I use only the dial, rather than
the button plus the dial.

I am surprised that no one has commented on the light rays from the moon.

This hasn't happened to me, and I hope it doesn't. I hope you get a good solution for this problem.

Well, Hmmmm....I have never had any of my Nikons go off of a setting unless I forgot to set something back from a previous shoot or simply hit a wrong button combined with a dial as stated above...AARRGGG!!. Is this a unique problem to the D750 (I don't own one) ?
So, why DOES it have a four ray star? What lens was used here?

I know this is just me, but I'm more curious as to the image appearing to have camera movement and also out of focus upon downloading the image. Also, just me critiquing (I know, I know! You didn't ast for a critique - I belong to a Critique community on Google +, so I get carried away sometimes!) the centering of the subject (moon) just doesn't feel right (I know, rules - of thirds - are made to be broken, I don't feel that here).

I'll apologize in advance if I've stepped on any toes here!!
Ciao!

No, not at all. I didn't set out to take a great photo, just messing around. The focus may be off; it just may be the low light, it might be because it was hand held. It may also be because I took it with the lens pressed up against a fine threaded aluminum screen, which caused the moons rays to appear as it did. I looked at the view on the screen and really wasn't impressed with it and moved on. The next day I down loaded it to the computer to play with it and see if I could make anything of it in post processing. That's when I noticed that they were jpeg files and not RAW which is what I always shoot. I posted the photo just for the hell of it figuring I'd get asked about the moon rays at the same time to see of anyone else was experiencing the same behavior with the D750. It is the second time it's done it to me. The first time was a year and a half ago during my son's graduation. I caught the problem seven shots after it switched itself to the jpeg format.

The lens used here was the Nikon 35-70mm f2.8 AF zoom lens.

Let's hope you find a simple solution for that RAW/JPEG shift!
